I’ve worked at “Big G” and a startup - big tech is a much more sane place to start a career than a startup. If you just graduated, it’s a good place to learn basic skills before considering a startup job.

Google for example is much more rigorous with code reviews and code quality. They maintain a high % test coverage, continuous integration and delivery… etc. startups can’t maintain those same standards and move quickly. learn the rules before you break them.
